摘　　要：基于MSC-Marc软件建立弓网系统模型,对受电弓-接触网动态振动性能进行仿真研究。建立接触网、受电弓两个系统的有限元模型,模型之间通过接触实现耦合,使弓网作为耦合系统进行低速条件下的动态仿真。将结果与国外仿真、实测及运行结果相比较,验证软件分析的正确性。在此基础上,针对我国京津城际铁路受电弓-接触网系统参数,对高速下的弓网系统动态振动性能进行仿真,分析影响弓网受流的主要参数,得到高速下接触网动态抬升量、弓网接触压力及离线现象,并通过参数的调整保证弓网可靠作用达到良好受流性能。对高速受电弓与接触网的相互作用进行大量的仿真并对结果进行分析,为进一步研究高速下不同受电弓与接触网参数的配合奠定基础。A novel finite element method（FEM） simulation approach to dynamic interaction of the high-speed pantograph-catenary system is presented. On the basis of the MSC-Marc simulation platform, the coupled FEM model of the pantograph-catenary system is established and the interactions of the coupled model at normal speeds are simulated and compared with results of Frohling＇s simulation, field measurement and operation practices to verify the correctness of the approach. Taking into account the pantograph-catenary parameters of the Beijing--Tianjin Intercity Railway, the model simulates dynamic interaction performance of the pantograph-catenary system under high speed operation. The main parameters affecting current collection are analyzed. The dynamic uplift of contact wires, pantograph-catenary contact force and loss of the contact force are obtained. Good current collection is achieved by modifying relevant parameters. Good basis is laid for further study on matching of parameters of contact wires and different pantographs at high speeds.
